Scattering of radio waves in a plane linear layer

Solution of the ray-tracing equation by the perturbation method for a plane­ stratified linear model of the ionosphere is considered. The first-approxima­ tion solution for isometric and anisometric Gaussian random inhomogeneities is used in a computer calculation of the second-order moments of the emergence direction of the wave leaving the ionosphere, and their functional relation to the average geomagnetic latitude and azimuth of the radio path is established.
